    I have been doing some research on the same couple other things to touch on make sure your within the right frequency range 35-40 Hz (40 preferably.) I did come across this and I have been toying with the idea only because it would fit longer ar parts.

    Here's a good article that should help information wise when choosing an ultrasonic cleaner also Grizzly industrial has a lot of good options.

    Sound advice, but unfortunately I do not have $3000 for the one I would then purchase...

    Looks like a few of you are pretty happy with the Harbor Freight model, so that will certainly warrant a good looking at. Being a somewhat mechanical person by trade, I just have a hard time taking anything from that store seriously. I also know how expensive shopping by a name can be, and doesn't always carry with it any certainty as to the quality. In this case, the Lyman model is around $140, where the Harbor Freight model is around $80, and they look very similar, as if they might actually be the same machine under a few aesthetic differences? Thank you for that feedback...

    As to my aluminum question, I guess it is either a myth, or misunderstanding, perpetuated by your normal online channels of panic. I would go with the latter since I have seen AR's and other aluminum parts being cleaned in ultrasonics. Looks like it could have been a problem at one point, but was easily remedied by a better understanding of frequencies and proper Ph balance? Thank you again for your advice and guidance on that one!

    After looking at the Grizzly web sight, which I had long ago forgotten all about until you guys just reminded me, I found something along the lines of what I want to build up to...

    Again, start with something more economical, and work my way up to the bigger toys...

    From what I have read aluminum is used to check if your setup is correct. If it quickly pops holes in the foil and tears it up you are good to go. Aluminum is soft and the bubbles are like little detonations. Same way ping wrecks engines.

    Actually, my original question wasn't about the foil, but something to the effect the cavitation has on aluminum alloy at a molecular level? In one Youtube video I saw, the guy was very insistent as to "NEVER NEVER NEVER" put aluminum parts in an ultrasonic cleaner, and that wasn't the first time I had heard something along those lines. Think it was just one of those old-wives tails as I have seen time and again examples of using ultrasonics to not only clean aluminum gun parts, but automotive parts as well. That's why I think I can conclude, for now anyway, that some of the issues of the past were more about the follies of using the wrong cleaning compound, and possibly frequency issues with earlier generation machines.
